the only reason dune-istl was required was that the spline class used
ISTL's tridiagonal matrix. Since the spline class moved into the core
(along with a more capable tridiagonal matrix), ISTL is no longer
required by opm-material.
Otherwise the compiler will probably give us a warning that these
pragmas are unknown. By default that warning is disabled with our
own build system, but we also want to be able to link to our library
without incorporating the entire build system too.
When doing a private install of DUNE libraries, the dune.module file
is put in the lib/ directory, regardless of architecture.
This patch searches the lib/ directory as a catch-all after having
searched the platform-specific directories. This should minimize the
chance of hitting an accidentally unrelated dune.module.
To avoid deprecation warnings the number of smoothing steps was passed
through the Criterion instead of directly to the constructor in commit
a7f32b934b.
However, due to an insufficient test matrix this was not tested using
the fast AMG variant of DUNE so it breaks the builds if
`-DHAS_DUNE_FAST_AMG` is defined.
This change should apply the same type of change to this branch as for
the others. The number of smoothing steps is put into a constant to
avoid the magic number 1 to appear in too many places (although I am
not sure the number for pre- and post-smoothing always should be the
same).
If the library is found, but dune.module is not, we really should give
an error because the #ifdefs in the code will not work as intended.
Print the locations where we expect the library to appear to the console
for better tracking.
These functions are referred to from templates which may not be
instantiated. Since they were in an anonymous namespace they were
not reachable otherwise, and a warning is emitted. This only applies
to Clang; GCC consider them used.
If we make them static helper functions instead, the warning
disappears.
If a function is used by a template but this template is not
instantiated, the function will still be defined in the header
of a module but it won't be callable because it is in an anonymous
namespace and thus we get a warning.
This only happens in Clang; GCC consider functions referenced from
templates as used.
fixup! Don't warn about functions not emitted
The CMAKE_NOT_USING_CONFIG_FLAGS option is really only settable by a
user that doesn't want _DEBUG or _RELEASE flags to not have effect.
If we want other flags than the platform default, we must do hairy
things like clearing them from the cache (overriding the user's
seletion if it was the same as the platform default).
The operator precedence in CMake can be surprising, so add parenthesis
to make in unambigious. Also, make it more explicit from which language
we get the default options. (They are all set from the settings given
for C++; why would have different optimization options for C and C++?)
As of 2013-09 the DUNE code that reads dune.module is not MultiArch-
aware. Thus, for a 64-bit platform it will look in lib/ on Debian and
lib64/ on RHEL.
Some components are not yet MultiArch-aware and installs to either
lib/ (Debian) or lib64/ (RHEL) on 64-bit platforms. If we need to
interface with these components, then it is nice to have such a
variable set together with the regular detection code.
During configuration some of the values for CMake properties (compiler
flags etc.) may be changed either by the user (through command line
parameters or option files), or by the configuration script itself
(setting more aggressive options or detailed debugging for instance).
This change writes many of the relevant values back into the cache so
they are available for introspection (using e.g. ccmake) or when the
rerunning the configuration without specifying all options.
